Technical conceive of the present utility model is: according to the electric discharge dressing principle, but utilize the characteristics of metal bonded wheel conduction and ablation, with the electric spark precision truing method wheel grinding surface bond matrix material is removed, realization is to the shaping of wheel face.
The purpose of this utility model is at the processing of the accurate grinding of difficult-to-machine materials such as hard brittle material, composite, and particularly profiled surface grinding provides a kind of shaping methods of metal bonded wheel.It is adapted to the shaping of various abrasive materials, different shape, various granularity metal bonded wheels, and after the shaping end, grinding can be carried out at once, need not to dismantle emery wheel, so shaping efficient and plastic precision height, the grinding state is good.
The processing method of the complex surface knife tool that the utility model provides comprises electric spark precision truing, Elid method for grinding.
Described metallic anchoring agent abrasive wheel electric spark precision truing is characterized in that, it may further comprise the steps:
(1), metal anchoring agent diamond wheel joins by anode fixture and high frequency pulse power supply positive pole and does anode, tool-electrode and high frequency pulse power supply negative pole join and do negative electrode;
(2), between emery wheel and tool-electrode, feed media with conducting the two poles of the earth and cooling effect, electric spark can be produced between emery wheel and tool-electrode, owing to need shaping to go out to have the emery wheel of complex profile, so very high to technological requirement, the electric spark precision truing technology of indication is exactly the electric spark precision truing technology that the utility model people formulates voluntarily in the utility model: the electric discharge dressing process of complex profile emery wheel.
(3), continuously by electric spark precision truing ablation emery wheel surplus.

Description of drawings
Fig. 1 is the schematic diagram of metallic anchoring agent abrasive wheel electric spark precision truing device.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of metallic anchoring agent abrasive wheel electric spark precision truing device, comprise frame, metal bonded wheel 1, tool-electrode 2 and high frequency pulse power supply 3, described metal bonded wheel 1 and tool-electrode 2 are installed in rotation on the frame, described metal bonded wheel 2 be positioned at tool-electrode 2 directly over, the top of described tool-electrode 2 and described metal bonded wheel 1 leave discharging gap between bottom, at described discharging gap side high-pressure spray gun 4 is installed, described discharging gap is aimed in the outlet of described high-pressure spray gun 4, described high-pressure spray gun 4 can be installed on the guide rail 5 slidingly, described guide rail 5 is fixedly mounted on the frame, described high-pressure spray gun 4 is provided with high-pressure air pipe and water inlet pipe, the top of described metal bonded wheel 1 is provided with oral siphon, the positive pole of described high frequency pulse power supply 3 is electrically connected with described metal bonded wheel 1, and the negative pole of described high frequency pulse power supply 3 is electrically connected with described tool-electrode 2.
At first require to design tool-electrode according to cutter, utilize tool-electrode that emery wheel is carried out electric spark precision truing then, metal anchoring agent diamond wheel is connected as anode with positive source, tool-electrode and power cathode join and do negative electrode, open the electric spark precision truing high frequency pulse power supply, according to technological requirement, feed media: can be water, high-pressure water mist, pressure-air etc., allow emery wheel slowly descend simultaneously, utilize electric spark that the metallic bond on the ablation emery wheel abrasive material surface of emery wheel is removed, thereby reach purpose the shaping of metal anchoring agent diamond wheel high efficiency high accuracy.
For the high-precision purpose of the high efficiency that reaches electric spark precision truing; general, the media in pre-shaping stage, finishing shape stage is a water, because water can be taken away very most heat; so the surface quality of emery wheel is best; the small metal particles of these two stage electric spark precision truing ablations can reduce the loss of tool-electrode, in experimentation attached on the tool-electrode simultaneously; can adjust the flow of water; control spark discharge state increases discharging gap, reduces the clearance of emery wheel.
